SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No.

Application filed May 10, 1901.

To (LZZ whom it may concern.-

Be it known that I, XVILLIAM II. BECK, of Griffin, in the county of Spalding, State of Georgia, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a complete specification, reference being had to the accompanying drawings.

The object of my invention is to provide means in a sewing-machine of driving it by hand as'conveniently and at as high and constant a rate of speed as by foot.

My invention is applicable as an attachment to any type of machine now in general use or it may in the process of manufacture be incorporated as a part of the original structure of a machine.

The driving of a machine by foot-power is excessively laborious to many persons and positively injurious to some. It is to avoid the necessity of the use of foot-power that my invention is designed.

In the accompanying drawing I illustrate a transverse vertical section of a complete machine with my device applied thereto, the head of the machine being indicated in dotted lines.

Referring to the numerals on the drawing, 1 indicates one of the end frame-pieces of a sewing-machine; 2, the table thereof; 3, the driving-wheel, carried upon a crank-shaft 4 in the frame 1; and 5, the driven wheel operatively united to the driven wheel 3, as by a belt 6.

The parts enumerated represent such as are found in every ordinary type of machine.

696,400, dated April 1, 1902. Serial N0. 59,658. (No model.)

7 indicates a lever provided with a handle 8, to which, nearits middle, is looselypivoted, as indicated at 9, one end of a pitman 10. The other end of the pitman is pivotally united to the crank 11 of the crank-shaft 4,

for which purpose the said end of the pitman is bifurcated to receive the crank and is terminally closed, as by a journal or spacingblock 12, secured in place, as by a bolt 13. The lever 7 is located in front of the machine and fulcrumed near its lower end, as indicated at 14, to the frame of the machine or some member attached thereto. I prefer to apply the fulcrum to the treadle 15 0f the machine, which for that purpose is disconnected from the pitman which ordinarily connects it with the crank 11 and is reversed, as shown in the drawing. It thus loses its function of a treadle altogether and becomes merely a fulcrum-support for the lever 7.

What I claim is- As an improved article of manufacture,sewing-machine driving mechanism adapted to be applied directly to any ordinary sewingmachine, consisting of a lever adapted to be fulcrumed at its lower end to the reversed treadle of a sewing-machine, and a pitman movably secured midwise to the lever at one end, and adapted at its other end to be secured to the crank of the machine.

In testimony of all which I have hereunto subscribed my name.

ZILLIAM H. BECK.
